The Derby Duo contains two of Buddy's most famous instrumentals. Now you can learn to play "Nightlife" are your E9th neck with only 3 standard pedals and two standard knee levers. There's also a great track and a super vocal version that you play your own files too. A slower version of Night is also supplied. The second song is Mike's version of "Blue Jade" with instrumental and tracks. These are in the original keys.
